182749 VIDEO AND PIC WEBSITE

I am needing a system for users to upload [login to view URL] videos to my website. This will allow users to grab the embed tag from [login to view URL] videos and upload that code and auto embed it into various pages on my website. I have built all of the pages already, or most of them. but i am going to need to be able in some way to add this scrpit to new and additional pages. This also needs to be a system where my users register before uploading the [login to view URL] embeding. and also I need it to be able to let them upload photos onto specific pages, and these photos need to be saved on the users profile page on my website. Im going to need to be able to add this upload script to new pages daily to allow users to upload to new pages when i create them. each users video and photo uploads also need to be able to be loaded aotomatically onto his or her profile page onmy website thats is created when they register on my site. similar to how youtube does it themselves. but also with images uploadable, like myspace does it. The key here really is for me to be able to add this system to new pages when i create them in a semi easy manner, and have it all work smoothly still. The user pages need to be able to be updated by the user for layout changes like myspace layouts. where the code is changed, but the background image is hosted elsewhere, like myspace does it.
